Frequently Asked Questions
Q: Which LoRaWAN network servers is the E870-S compatible with?
A: The E870-S runs the Semtech UDP Packet Forwarder and is compatible with TTN (The Things Network), Helium, ChirpStack, AWS IoT Core for LoRaWAN, and Ebyte’s private LoRaWAN server. Configuration is done via the built-in web UI.
Q: What is the difference between half-duplex and full-duplex LoRaWAN gateways?
A: A half-duplex gateway (like the E870-S) cannot transmit and receive simultaneously on the same channel. It is cost-effective and sufficient for most IoT deployments where end nodes transmit infrequently. Full-duplex gateways support simultaneous TX/RX and are suited for high-density or time-critical networks.
Q: How do I connect the E870-S to the internet?
A: The E870-S supports two uplink methods: wired Ethernet via RJ45, or wireless WiFi STA mode (connects to an existing WiFi router). Both can be configured through the web UI accessible at the gateway’s local IP address.
Q: Which frequency variant should I choose for my region?
A: Choose E870-L470LG12-S for China (CN470, 470–510MHz). Choose E870-L868LG12-S for Europe (EU868, 863–870MHz). Choose E870-L915LG12-S for North America / Australia (US915, 902–928MHz). Frequency bands are hardware-fixed and cannot be changed after purchase.
Q: How many end nodes can the E870-S support?
A: A single E870-S gateway can theoretically serve thousands of LoRaWAN end nodes, as LoRaWAN is designed for low-duty-cycle devices. Practical capacity depends on the transmission frequency and payload size of each node. For dense deployments, multiple gateways can be deployed with overlapping coverage.
